How to Wash: Laundry Symbols

Scan the care label on any garment and get plain washing instructions. Then pick the stain you are dealing with and get the steps that remove it from that exact fabric.

Everything runs on your iPhone. There is no account and no sign-in.

WHAT IT READS • 40 ISO 3758 care symbols, across washing, bleaching, drying, ironing, and professional cleaning. An on-device model recognizes them from the photo. • Fabric composition in 7 languages: English, French, Spanish, Portuguese, Italian, German, and Dutch. A label listing cotton, coton, cotone, and Baumwolle resolves to one composition. • The temperatures and cycle text printed next to the symbols.

HOW IT WORKS 1. Photograph the care label. 2. Check the symbols it recognized. Correct anything that is wrong before you continue. 3. Photograph the stain, or pick its type from the grid. 4. Read the result: temperature, cycle, bleach, drying, ironing, dry cleaning, and the stain method for that fabric.

If the garment has no label, start from the fabric instead and get the same advice.

STAIN REMOVAL • 60 stains across beverage, food, body, outdoor, cleaning, and other categories. • 20 fabrics, from cotton and denim to silk, wool, cashmere, and technical shells. • Rules for the combinations that ruin clothes: blood on silk, grease on wool, red wine on cashmere, ink on denim. • Steps in order, with the ones that set a stain called out first.

REFERENCE • A library of all 40 supported symbols, with what each one means and what to do about it. • A stain guide you can read before anything is spilled. • Every scan is saved on your iPhone, grouped by Today, This week, and Earlier.

PRIVACY Symbol recognition, label reading, and stain advice all run on your device. No account, no analytics, no advertising. Photos of your labels and stains stay on your iPhone. The only network traffic is subscription billing through Apple.

NOTES • Reads ISO 3758 symbols, the international standard used in Europe and on most imported garments. ASTM-style American symbols are not supported yet. • Requires iOS 26 or later. iPhone only. • The advice is informational. Check the manufacturer’s instructions on the garment itself.
